The Reinforced Carbon Piston Head FPS Softair X-RING (XPAVPCF) is made from a technopolymer reinforced with carbon fiber and is specifically designed by Italian company FPS Softair to reduce gearbox noise and support high rates of fire (ROF). It is suitable for airsoft guns with a firing rate above 30 rounds per second and helps decrease mechanical stress and noise by reducing the piston's weight. The unique front design prevents ventilation holes from closing and maintains an optimal air volume between the cylinder head and piston head, creating an anti-vacuum system without sacrificing power.
